power of hydrogen

Question 1

the power of hydrogen’s ph

Answer 1

Hydrogen (pH) scale is a numerical scale ranging from 0–14.
It is used to compare the acidity of solutions.
– A solution is considered more acidic than another if the dissolved
compound within it released more hydrogen ions, which in turn produced
more hydronium ions.

Question 2

acids soultions

Answer 2

ph<7

Question 3

neutral soultions

Answer 3

ph=7

Question 4

basic soultions

Answer 4

ph>7

Question 5

hydrogen vs hydroxide

Answer 5

• The pH scale provides a measure of how acidic or basic a solution is based on the relative
  concentrations of hydronium ions and hydroxide ions in solution.

Question 6

concentration

Answer 6

– Concentration is the abundance of a substance in a given volume of solution. * If the solution has a greater hydronium ion concentration it is acidic, and if the solution
has a greater hydroxide ions concentration it is basic.

Question 7

soultion’s on basic,acdic,hydrogen, and hydroxide

Answer 7

acdic solution:[H ] 3O+] > [OH–,

neutral soultion: [H3O+] = [OH–

basic soultion: [H3O+] < [OH–
]

Question 8

water

Answer 8

Water is neutral because it contains equal quantities of hydronium and hydroxide ions.
Note: Water reacts with itself because it is amphoteric

Question 9

ph scale

Answer 9

The pH scale was developed by Danish chemist Søren Sørensen in 1909. The
scale is used to compare to the concentration of hydronium ions in different
solutions.
* The values on the scale increase or decrease exponentially (by a factor of 10)
as you move up or down the scale.
